Be it known that l, HENRY Vnmin'nn, a citizen of the United States, residing in the borou h of lilanhattan, city, county, and State of New York, have invented a new and useful Improvement in Tobacco Pipes, of which thetollowing is a specification.

This invention relates to tobacco pipes and particularly to an a tachment for pipes, by means of which any ordinary pipes can be converted so as to give to the user cool, sweetsmolre.

Among the objects of my invention may be noted the following: To provide a tobacco which the heat, in the the process of smoking,

pipe with means by burning tobacco in may be extracted or removed and prevented from reaching the mouth of the user; to proidde atobacco pipe with means by which the nicotine carried in the smolre mav be deposited in the pine so that none of it will reach the mouth of the user; to rovide an attachmentfor ordinary pipe, by means of which, with very little it any alteration in the struc ture of the pipe, the latter may be rendered capable o1 extracting the heat the smoke in its passage to the mouth of the user and of deposi ing the nicotine so as to prevent it from reaching the mouth or the user; and to provide certain details of construction whereby the foregoing objects ined simply, economically and readily.

lVith the above objects in view and others which will be detailed during the course 01 his description my invention consists in the parts, features, elements, and combinations of the latter as hereinafter described and claimed.

in order that my invention may be clearly understood, 1 have provided drawings wherein:

Figure 1 is a longitudinal section of an ordinary tobacco pipe with my invention applied thereto;

Fig. 2 is a perspective view of the attachment o1 my invention; and

Fig. 3 is section substantially on the line 3-3, Figure 1.

Referring to the drawings, the numeral 1 indicates the bowl of an ordinary pipe; 2, the thereof; and 3, the bit or mouthpiece having the usual reduced extension d, adapted to enter the usual bore in the stem of the pipe, the bit being held frictionally iu the stem as usual. In the bowl of the fLetters Patent Fit-tented Jai 17, 1922.

its bottom, is the usual passage 5 seen that my invention consistsof a plug of peculiar form and structure, set by medium 0t its screw-threaded end 6 in the bit-extension l, and'havinpa passage 7 which continuesthe passage 8 through the stem clear into th enlarged head 9 of the plu At the base of the screw-threaded extension 6, a flange 10 is provided which is adapted to nan the diameter of the chamber in pipe, so that between the wall amber and the circumference ere-ch 9 t ien e plug is in position in the chamoer the stem 2 said chamber is divided into large chamber 13 and a smaller chamber 1%, by the head 9 of the plug, said chambers being connected by the very narrow passage 15. passages 12connect the chamber 1% with the end of the passage 7 which, by being extended beyond the terminal 01"- the passages 12, forms a small chamber 16. The re .ilt is that the smoke in passing from the base of the bowl 1 to the mouth of the user of the pipe traverses a circuitous path.

The plug is made from material which will absorb either heat or moisture. Consequently, it will not become saturated or fouled and *ill not expand so as to cause the head 9 to contract the passage between along the stem to the chamber in iiei erring to Figures 2 and 3, it will be abut i t the inner end of the bit-exten iere is avery small clearance d'ameter oft-he head 9 is slightly the chambers 13 and 14. The mode of operation and the function of the various features of construction are as follows:

The tobacco being lighted, the user draws upon the pipe in the usual way causing the volume of smoke to traverse the passage 5 carrying with it its usual concomitants of heat and nicotine. The smoke on reaching the chamber 13 expands, thereby releasing the heat to a very great extent and causing a deposit of nicotine and moisture in the chamber 13. The smoke then passes between the head 9 and the wall of the chamber 13 into the chamber 14:, where it again expands releasing heat and depositing such nicotine and moisture as may still be carried. The smoke then traverses the passages 12, entering the chamber 16 at the end of the passage 7, whereupon it again expands, releasing heat; and by the time the smoke enters the passages 12 all nicotine and moisture have been released and very little or no heat remains. The smoke then traverses the passage 7 and 8 to the mouth of the user, and by. the time it reaches the latter it is cool and sweet. The functions just described result ing from the disposition of the plug in the stem ofthe pipe are important to my invention since the plug compels the smoke to traverse a circuitous path before it can reach the mouth of the user and strips the smoke of all noxious fluids or in" redients and of practically all the heat. ence, the head 9 and its relative size together with the several chambers and narrow passages are important features of my invention upon which I desire to lay. stress.

Having thus described my invention what I claim and desire to secure by Letters Patent is: r

1. A pipe having a chamber in its stem and a passage therefrom to its 'loowl, said chamber having therein a centrally disposed plug which is supported out of contact with the walls of the chamber; said plug having a head slightly smaller in diameter than that of the chamber and disposed substantially midway of said chamber with its closed end toward the bowl of the pipe; said plug-head having a chamber therein and a reduced cylindrical member extended therefrom and secured centrally to the bit of the pipe, said member having a central passage in con tinuity with the passage through the bit and terminating in the chamber of the head; and said head having a plurality of inclined passages extending from its chamber toward the bit and into the stem-chamber.

2. A tobacco pipe having a chamber in its stem and a passage'extending therefrom to its bowl, said chamber having therein a centrally disposed plug which is supported out of contact with the walls of thechamber; said plug having a cylindrical member with a flange at one end and ahead at the other end, said plug also having a screw-threaded extension, and a central passage from one end thereof into the head; said plug also having a plurality of inclined passages ea:- tending to the passage in said head, and said head being slightly smaller in diameter than the diameter of the chamber in the stem of the pipe.

3. An attachment for tobacco pipes consisting of a cylindrical device formed into a head having a chamber therein, a reduced portion terminating in a flange, beyond which is another screw-threaded reduced er;- tension, said head having the chamber located centrally therein from which extends a passage through the reduced and screwthreaded portions, and said device having a plurality of inclined passages extended from the chamber in the head to the circumference of the reduced portion adjacent thereto.
